Company profile

researched Aug 2026

Across is a crosschain bridge protocol that lets users and applications move tokens between supported blockchain networks, offering both bridging and swapping in a single flow. Its website describes an intent-based design in which a permissionless relayer network competes to fill user transfers, with transactions verified onchain and no multisig or custodial control of user funds. The company states an average time of 1.2 seconds from confirmation to funds arriving in a wallet, with most transfers settling in under two seconds. The current product generation is marketed as Across V4.

Alongside its consumer bridging interface, Across offers an API that developers can integrate to add crosschain bridging and swapping to their own applications. Documentation examples show a quote-and-swap flow via app.across.to endpoints using origin and destination chain IDs (for example Base to Unichain for a USDC transfer). The protocol advertises support for a broad set of networks including Ethereum, Arbitrum, Optimism, Base, Polygon, Solana, zkSync, Linea, Mode, Lens, Lighter, Lisk, Zora, World Chain, Ink, Soneium, Unichain, BNB Smart Chain, HyperEVM, HyperCore, Plasma, Monad, MegaETH, Tempo, Tron, Avalanche, and Robinhood Chain.
